Washroom sealing for commercial buildings in Sompting

Accessible toilets, shower rooms and changing rooms have joints that work harder than most: wet-floor edges, tray perimeters, basin tops and the line where flooring meets the wall. Gaps in those places let water get under the floor or behind panels so they get particular attention. Site teams most often ask us about shower tray joints that have opened up and sealant stained black around basins and showers, across vanity units and basins, accessible toilets and changing rooms and kitchens and tea points. A specialist sealant contractor works differently from a general builder: in Sompting, that means joint design, primers and backing rod as standard.

Pub and restaurant kitchens around smaller places like Sompting work hard on their joints. Sealed joints at sinks, worktops and splashbacks help keep the kitchen cleanable, using a food-safe product near food preparation.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

What the job involves on each surface

Showers and trays

Shower trays move under foot and are wet all day. Tray joints are where many washroom leaks start.

Changing rooms and gyms

Showers, floor edges and vanity units in changing rooms all need sound sealant and we look at them as one job.

What happens if it’s left?

Gaps and mould in joints give dirt and bacteria somewhere to sit which matters most in healthcare, food and education settings. A smooth, sealed joint can be cleaned properly. Small buildings around Sompting suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote once you have the details.

What you get with us

  • Constructionline member

From enquiry to sign-off

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself typically taking between a morning and a week or so, set by the number of rooms and the phasing you need. Work in places the size of Sompting is planned as a single visit where we can. Clear photos and measurements help us bring the right products.

  1. We inspect each washroom and record the joints to be resealed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Joints are degreased and dried.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Rooms reopen after the cure time.

Preparing the site

  • Move anything stored against the joints
  • Send any specification or drawings in advance
  • Let building users know which areas are affected

Honest limits

Honesty saves time and money. Fresh joints won’t solve:

  • Water from plumbing, not from a joint
  • Panel boards already damaged by water
  • Water escaping beneath the floor rather than through a joint

If in doubt, phone 01277 525 020 or send photos by email and we will say what we think before you book.

Where we work in Sompting

  • Urinals and WCs

General trades versus a specialist

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Clean sealant with gentle products and a soft cloth
  • Photograph and log failed joints across the estate
  • Add sealant joints to planned maintenance checks
  • Share your site rules when you send details

Each room goes back into use only when the sealant has cured enough. We will tell you when the wet areas can be used, and it helps if signs stay up until then.

A few failed joints can be resealed with hardly any disruption. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.

Washroom sealing around Sompting: points for this area

The sea is no more than about 2 miles from Sompting, and coastal hotels, guest houses and holiday sites tend to fill up in the busy months. Bathrooms turned round daily in the busy months need sound, cleanable joints, which is why off-season resealing makes sense. Sompting has several hotels close by, all within 2 miles. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. We work a handful of rooms at a time, so the hotel keeps letting the rest.

If you manage an office at a site such as Rectory Farm Road Business Park, less than half a mile to the north of Sompting, the washrooms and tea points can be done a floor at a time. For a college such as Northbrook College (1.7 miles west of Sompting), half-term and summer give the windows for washroom work. At a hospital like Worthing Hospital, which lies south-west of Sompting, patient and staff washrooms are best done in short phases agreed with the ward.

Questions we are asked in Sompting

Is Sompting too far out for you?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Do hotels near Sompting have to close for sealant work?

In most cases no closure is needed: we work room by room or floor by floor. We agree the order of rooms and the timings with you before we start.

Do you guarantee washroom sealing?

A 12-month guarantee covers the work. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.

How long does a typical visit take?

The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

Do you need to see the site first?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.

Do you offer coloured sealant?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
